Road signs in Mongolia

Road signs in Mongolia are similar to the Soviet (post-Soviet states) and other European road sign systems. Road signs are regulated in the MNS 4597:2014 standard and conform to the general pattern of road signs as set out in the Vienna Convention on Road Signs and Signals. Despite the fact that Mongolia was never part of the Soviet Union, the MNS 4597:2014 standard for road signs has many similarities with its post-Soviet counterparts based on the Soviet standard ГОСТ 10807-78 and the Russian standard ГОСТ Р 52290-2004. Mongolia acceded to the Vienna Convention on Road Signs and Signals on December 19, 1997.

The Arial Bold typeface is used on road signs in Mongolia. Unlike most post-Soviet states, Mongolia does not use the typeface based on the ГОСТ 10807-78 Soviet standard. The Arial Bold typeface is also often used on road signs in Russia and post-Soviet states since it is a computer font and is included with all PCs running Microsoft Windows and Apple's macOS.
